Unstable behavior of hydrogen-air lean premixed flames (Effects of unburned-gas temperature, heat loss and scale)

open access: yesNihon Kikai Gakkai ronbunshu, 2020
Unstable behavior of hydrogen-air lean premixed flames was studied by numerical calculations of two-dimensional unsteady reactive flow to clarify the effects of unburned-gas temperature, heat loss and scale. We adopted the numerical model containing the

HEAT LOSS DURING ANAESTHESIA

open access: yesBritish Journal of Anaesthesia, 1978
The superficial and deep body temperatures of 23 patients were studied during prolonged anaesthesia for microscopic surgery of the fallopian tubes. The patients were divided randomly into three groups, receiving either halothane 0.5%, halothane 1% or low-dose fentanyl as a supplement to nitrous oxide, oxygen and myoneural block.
